I have a query about the Greek letters and math symbols available in
Stata graphics, and listed in -[G-4] text- under "Full list of SMCL tags
useful in graph text". Do these have Unicode numbers consistent between
operating environments? Or do they correspond to different Unicodes in
different operating environments, and/or even look a bit different
between Windows, Unix and MacOS?

I ask because I would like, ideally, to be able to use them in
automatically-generated tables (or maybe even in automatically generated
text) in automatically-generated RTF documents, such as the ones
produced using my own SSC package -rtfutil-. I can look up individual
Greek letters on the Unicode site at

but I would prefer to be able to insert, at will, all the symbols
available in Stata graphs, especially when presenting the same
information as a plot and as a table in the same document. I haven't
managed (so far) to find any information on this kind of thing on -help
undocumented-.
